Awww nath,
Had I thought of it you could have come to ours last thursday, MrsFrog wisely decided not to come.
You could have had one free drink, eaten crap food, listened to dodgy music and talked to the people you already spend far too much of your life with.
I'd prefer a little christmas bonus for the money, to treat MrsFrog with.
I sincerely hope that next year we just go down the pub, have good wholesome grub and a tab behind the bar, it will be cheaper and 100 times better.
